Valid Accounts: Cloud Accounts

Description from ATT&CK

Adversaries may obtain and abuse credentials of a cloud account as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion. Cloud accounts are those created and configured by an organization for use by users, remote support, services, or for administration of resources within a cloud service provider or SaaS application. In some cases, cloud accounts may be federated with traditional identity management system, such as Window Active Directory.(Citation: AWS Identity Federation)(Citation: Google Federating GC)(Citation: Microsoft Deploying AD Federation)

Compromised credentials for cloud accounts can be used to harvest sensitive data from online storage accounts and databases. Access to cloud accounts can also be abused to gain Initial Access to a network by abusing a Trusted Relationship. Similar to Domain Accounts, compromise of federated cloud accounts may allow adversaries to more easily move laterally within an environment.

Once a cloud account is compromised, an adversary may perform Account Manipulation - for example, by adding Additional Cloud Roles - to maintain persistence and potentially escalate their privileges.
